DvFilter module is not up on the host

Working at a customer site last week, we were looking at deploying vCloud Networking and Security App into the test environment.  Sounds simple right?  Well, when we went to install App, we had the error DvFilter module is not up on the host. As you can see by the screen shot below

DvFilter Module is not up on the host

After a little bit of digging around, we discovered the following KB article.

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1028003

This issue can occur due to a previous incomplete installation or due to problems during uninstallation.
To resolve this issue:
  1. Try the installation/uninstallation from the vShield plugin in vCenter Server. This provides detailed events when the installation fails.
  2. Verify if required modules are loaded in the ESX host before installing vShield App using one of these options 

Reading through the KB article, not all the commands are needed to resolve this issue.

To resolve the issue quickly, SSH to your ESXi host (5.x or above) and run the command:

#esxcfg-module –e /usr/lib/vmware/vmkmod/dvfilter

Then SSH to the vCNS Manager and run these commands:

enable
config t
no web-manager
reboot

You can then verify that the required components are installed on your ESXi host by running this command:

esxcli software vib list | grep -i vshield

Once you have followed these steps (quite a bit shorter than the KB article) you will see the issue is resolved and App is not installed.

    Hi, do you know how I find out where the vCNS is?

      If you mean where do I download vCNS from, you need to go to the downloads section at VMware.com
